James Alexander d. 1753 Rowan Co., NC

I am looking for information on a James Alexander and wife Ann who had land on James Cathey's Mill Creek and Coddle Creek in what is now Iredell Co., NC.Their children were William, James, Jr., David, Eleanor ("Ellen"), Robert, and John (although I have found no proof regarding John). Eleanor m. Samuel Rankin about 1760, and that line is fairly well-documented.I would appreciate any information about the other children or about James and Ann.
